인간 vs. 가상인간 인플루언서의 광고 설득효과 비교: 지각된 역량, 경험의 매개효과를 중심으로

안정용,성용준 한국광고학회 2022 광고학연구 Vol.33 No.8

This study was designed to examine the effects of human vs. virtual influencer on the advertising persuasion. An online experiement was conducted to test our proposed hypotheses that he interaction effects between influencer type (human vs. virtual influencer) and product type (utilitarian vs. hedonic). The results show that n the case of an utilitarian product, we found no signficant difference between human and virtual human influencers. In the hedonic product condition, however, the use of human influencer results in more positive persuasive effects (vs. virtual influencer). Further, the interaction effect between influencer type and product type was mediated by the perceived influencer's agency and experience. This study has practical significance in that it proposed a strategy to increase the advertising effectiveness of virtual influencers at a time when the use of virtual influencers is becoming important. In addition, there is a theoretical significance in that it reveals that there is a difference in perceived competence and experience between human and virtual human influencers, and that these two variables influence the influencer's advertising persuasion effect. 본 연구는 인간, 가상인간 인플루언서 간 광고 설득효과의 차이를 검증하고, 인플루언서 광 고 설득효과에 영향을 미치는 변인을 제안하기 위해서 설계되었다. 실험을 통해 인간, 가상인간 인플루언서 간 광고 설득효과가 제품유형(실용재 vs. 쾌락재)에 따라 다르게 나타난다는 가설을 검증하였다. 구체적으로, 인플루언서 유형과 제품유형 간 상호작용효과가 광고 설득효과 에 미치는 영향이 발견되었다. 실용재의 경우, 인간, 가상인간 인플루언서 간 광고 설득효과에서 차이가 나타나지 않았지만, 쾌락재에서는 인간 인플루언서의 광고 설득효과가 가상인간에 비해 높게 나타났다. 인플루언서 유형과 제품유형 간 상호작용효과는 지각된 인플루언서의 역량과 경 험에 의해 매개되었다. 본 연구는 가상인간 인플루언서의 활용이 점차 중요해지고 있는 시점에 서, 인간, 가상인간 인플루언서 간 소비자가 지각하는 역량과 경험 수준에서 차이가 나고, 이 두 변인이 인플루언서의 광고 설득효과에 영향을 미친다는 점을 밝혔다는 이론적 의의가 있다. 또 한, 인플루언서 유형 별 광고효과를 높이기 위한 마케팅 전략을 제안했다는 실무적 의의가 있다.

Nontraumatic, incracranial giant aneurysm has rarely been reported as the cause of the spontaneous subarachnoid hemorrhage in childhood. Multiple, dissecting giant aneurysms on the left middle cerebral artery with sudden onset of headache in a 14-year-old girl were successfully clipped and followed by complete relief of symptoms. The rarity and characteristics of such lesion in childhood and its successful surgical treatment are discussed briefly.

More than one cerebral aneurysm on the same artery is uncommon. Furthermore multiple aneurysms on the anterior communicating artery(ACoA) is very rare. We surgically experienced one case of two separate aneurysms on the ACoA ; one developed at the junction of the ACoA with the right second branch of anterior cerebral artery, and the other on inferior wall of the ACoA itself. The former, confirmed as ruptured on operation, projected superiorly and the latter directed inferiorly toward the prechiasmatic cistern. Radiographic and operative findings are presented with review of literature.

Objective : To evaluate objectively the sites of injury in patients with posttraumatic olfactory deficits and to suggest the diagnostic procedure for evaluation of posttraumatic anosmia. Methods : Ten patients with posttraumatic olfactory dysfunction were examined by means of olfactory testing, sinoscopy, contrast filled paranasal sinus computed tomography(contrast filled PNS CT) and magnetic resonance imaging(MRI). Five normal persons without olfactory dysfunction were also evauluated. The aerodynamic patency of olfactory cleft was examined by contrast filled PNS CT. The olfactory system(oflactory bulbs, olfactory tracts, inferior frontal region, hippocampi, or temporal lobes) was investigated in detail with MRI. The difference in the size of the olfactory bulb between normal volunteers and anosmic patients was evaluated by Student's t test. Results : Contrast filled dynamic CT scan was useful method for the evaluation of dynamic patency of the olfactory cleft. Paranasal CT scan of the all anosmic patients showed dynamic reflux of contrast media in olfactory cleft on valsalva maneuver. For the largest cross-sectional area and great height, the difference in olfactory bulb size between normal volunteers and patients was statistically significant(p<0.001) in MRI study. Conclusion : Posttraumatic anosmia was completely evaluated by olfactory testing, sinoscopy, and contrast filled CT scan for differentiation between conductive type and neurogenic type. Neurogenic anosmia was confirmed by perfect localization with MRI study.

Malignant fibrous histiocytoma is a rare malignant tumor of probably histiocytic origin. It is more common in soft tissue than bone. Usually it involves metaphysis or diaphysis of long bone. Primary spinal malignant fibrous histiocytoma is exceedingly rare. Authors report a case of primary malignant fibrous histiocytoma which showed rapid spinal cord compression in thoracic spine with review of literatures.

A case of unruptured cerebral aneurysm at the junction of accessory middle cerebral artery and the distal portion of the $A_1$ segment of the anterior cerebral artery is reported. To the authors' knowledge, this is the first reported case of cerebral aneurysm developed at the junction of accessory middle cerebral artery, demonstrated on magnetic resonance angiography(MRA). The accessory middle cerebral artery is a rare vascular variant of middle cerebral artery. Furthermore, it is extremely rare for an aneurysm to be developed at the origin of the accessory middle cerebral artery. The development of the accessory middle cerebral artery is very important in surgery of cerebral aneurysm and collateral circulation of cerebral infarction. Review of the literature regarding the genesis and anatomical variation of the accessory middle cerebral artery is also presented.

The authors report a case of atypical meningioma in the fourth ventricle. Intraventricular meningioma is not uncommon intracranial neoplasm, especially that in the trigone of lateral ventricle, however, those in the third and fourth ventricle are very rare. There are only two cases of atypical meningiomas in the fourth ventricle among 29 cases of fourth ventricular meningiomas reported 17 literature. The clinical features, findings of magnetic resonance image and operation of our case, and review of literature are presented.

Sixty-four patients with intracranial arachnoid cyst were treated at the Department of Neurosurgery, Yonsei University College of Medicine between 1985 and 1992. Among them, f e rty-eight patients received operation. The purpose of this study was to review our surgical results and find out the most effective surgical procedure for arachnoid cysts in each location. The thirty-one patients with the supratentorial arachnoid cyst showed the mass effect or subdural hematoma on preoperative CT scan. They were treated with marsupialization, cystoperitoneal shunt fenestration with cystoperitoneal shunt, and cystoperitoneal shunt with endoscopy. The fenestration with cystoperitoneal shunt showed the best result in supratentorial arachnoid cysts. The ten patients with the midline arachnoid cyst showed the hydrocephalus on CT scan. They were treated with open fenestration with ventriculoperitoneal shunt, endoscopic fenestration, open fenestration, endoscopic fenestration with ventriculoperitoneal shunt and cystoperitoneal shunt. The endoscopic fenestration showed the best result in midline arachnoid cysts. The seven patients infratentorial arachnoid cysts also presented with hydrocephalus on initial CT scan. The open fenestration with ventriculoperitoneal shunt, open fenestration, endoscopic fenestration, and cystoperitoneal shunt were surgical procedure for these. The cystoperitoneal shunt showed the best result in infratentorial arachnoid cysts. The complications of treatment related with shunt operation, were relieved with shunt revision. Forty-five cases among fortyeight operated cases had good clinical outcome. The most appropriate surgical method for arachnoid cyst were discussed.
